I had to get an MTP done due to some complications in my pregnancy (I am 31). The procedure happened on 25th September. The doctor told me after the procedure that she had done an ultrasound and everything was clean. I had no complaints after the MTP (no cramping, excessive bleeding, etc). Now it's been 3 months and I still haven't gotten my periods. I visited my Dr. sometime back and she gave me some progesterone tablets, but it's been 8 days after finishing the course of that medicine and still my periods haven't started.

Is this okay to have a delay of over 3 months? What possibly can be wrong? Please advise as I can then ask my Dr. directly about the potential issues.
